DANIEL LAWRENCE BRAINE, OF BROOKLYN, NEW "YORK, ASSIGNOR TOTHE BAIL JOINT COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK METHOD OF FORMING- A COMPROMISE RAIL JOINT BAR Application filed June 5,

This invention relates to compromise or step joint bars for connecting and holding the ends of rails of difi'erent section, with the gage and surface of the rails in alinement, and has particular reference tovimprovements in bars of that type which are squeezed or pressed, i. e. bulldozed from rolled or forged bars or blanks, and to im provements in the dies and the method employed to produce said bars; A joint bar of the general type with which the present invention is concerned is disclosed in Armstrong Patent 1,663,619.

Bulldozing a bar or compromise rail joint bar involves reducing the height and vertically and laterally offsetting a portion of the bar to compensate for the difference in section and height of the rails to be united.

According to methods and means heret0 fore employed to produce a bulldozed compromise joint bar, squeezing of the bar to reduce the height of a portion thereof to provide the low fishing section invariably resulted in the web of the low fishing section being bulged. or caused to protrude out- 'wardly, which necessitated planing off or suitably removing the bulged metal, as otherwise the low fishing section of the bar would be too wide for the length of standard bolts, and a suitable bearing face for the heads and nuts of the bolts would not be afiorded. This machine step of planing or finishing the outer contour of the web of the bar not only involved considerable expense but resulted in weakeningof the bar and Variations-in the weight and strength of different bars.

Accordingly the present invention has in view on the one hand to provide for the manufacture of bulldozed compromise joint bars without the necessity of removing any metal from the bars following the bulldozing operation, and, on the other hand, to provide a bulldozed compromise joint bar in which the low fishing section of the bar will be at least of equal weight and strength to that of the high fishing section of the bar.

With the foregoing general purpose in view, the invention consists in the features of novelty as will be hereinafter more fully blank to produce a.

described, illustrated in the accompanying drawings and defined in the appended claims.

In the drawings, wherein like characters of reference denote corresponding parts in the different views Fig. 1 is a side elevation of a straight bar or blank from which a compromise joint bar is adapted to be produced by a bulldozing operation.

Fig. 2 is an end elevation-of the bar or blank shown in Fig. 1. I

Fig. 3 is a sectional view showing the bar or blank positioned in a holding die, im-

promise joint bar is to connect and hold the ends of a pair of rails of differentheight and section with their surface and gage in alinement. This is illustrated in.- Figs. 4

and 5 of the drawings wherein high and'low rails of different section are designated R, R, respectively, and the compromise joint bar is designated generally as B. Essentially a compromise joint bar is inclusive of high and low fishing sections of a height and section to fit the high and low rails, respectively, of the particular compromise or step joint combination of rails Win 1 which the bar is intended for use. These high and low I bar fishing sections are designated H and L in'the present instance and, as is usual, they are vertically and laterallyofi'set with respect to one another to compensate for the difference in'the height andcross section of the rails. According to general practice a compromise jointbar may bev produced in either of three ways-by casting, by forging, or by bulldozing.

The present invention is concerned with r bulldozed compromise joint bars, and to a a method and means of producing them whereby proper fishing fit of the :bar with the rails is secured and whereby the'obje'ction, as previously pointed out, concerning the necessity of planing off outwardly 'blilgedemetal, the "increased production cost resulting "from the necessity of this operation, and the variation in weight and strength of the bars is entirely eliminated.

In carrying out the invention-the usual practice is followed of providing a rolled Eur forged bar 'or blank having a straight rseoti'on, 'ithroughout its length, which #ma fit, or approximately fit the high railof the compromise or step joint combination of nails with *whichthe' bar is intended for use, it being understood, ofcoi'1rse,that the bar or iblank may be 0f any form desired so ilong as it is "susfieptib1e of being changed --into compromise form by a bulldozing operation. Such a bar or blanl'i is designated generallyzataAliniFigs. 1 a-nd"2 of the drawings, a foot flange form ofba-rhaving been .eelecte'd for purposes of illustration merely because of'ethevextensive useof tl'iis fo rm of bar. As usual, fsaid bar is composed essenltiallylofahead #10,:a web'lQandabase 14, which latter iis inclusive of :a I heel 16 and a -fnot :flange 1 8* terminating" in a :toe 20, the head lOeandithe heel .16 extending inwardly =beyond theiinner 'faceiof the web 1 2 in ac- .eordanc'e with "common 1pr'a'ctice.

ZFor bulldozing the bar A into compromisc form a pair :of vcooperating dies :D and D are employed, it beingundei'stood, 0f -oourseathattsuita'bl'e' means (notshown) =are provided for forcing one :said dies, -termed ithe "moving :Jdie, iD in this instance, towards the other or holding the D, to "efrfect lbull'dozing of :a bar or blank A "posiltioned between said dies.

.Heretofore it has 'been general practice "to form the impressions in the dies D :and Enso :thatithe :direction of relative move- "merit betweenthe adies, i. e. the direction of the k'bulldozing :pressure, .lparalleled or was aim-the plane Iof' the web of :the'ibar or blank A,*Wllll1 the :result that the web of-the'b'ar Mas bulged -=outwardly as aforestated. :As distinguished from this ,prior ,practice, the present invention contemplates, in its ibro'ader aspects, forming the impressions in the dies sothattheibulldozing pressure will be in a rdi'reetion ati-such an angle between 10 .and'9fl to1thefplane of the web of the-bar "that :alllbul'gingiof the-metal of the 'web due lto th'e bulldozing 7 operation will :be 1 directed inwardly, i. e.--'away 'fromtthe outer face of the web and towards Ithe sinner lface there'of. To accomplish :this purpose saty "to' the holding Consequently, when the :the result of shoving-the head '10 "thereof, reducing the height of a POIlZlOIlOf the bar and thus 'formingithe low ing die D in this instance, is provided with "a cooperatmg low fishing impression 1d" conforming only to "the inner contour of the toe, the base and the heel of the bar,

this impression being formed so that when a bar or blank A is squeezed between the diesthe'metal i'n the-web of the bar or blank is free only to bulge inwardly.

.Thus,'-when a-bar or blank A is positioned die'D-as illustrated in Fig. 3 o'ifthe drawings,- a face 22 of theimpression (Z conforming to the outer face of the web ofthe lowfishing section of the compromise bar'will prevent the web of the baror blank 'from bulging outward under. pressure of the moving die Dflwhile an opposite face2 lof said impression, conforming to the contour Ofthetop and the inner -face 'o'fthe headof the bar, as far as the lower .fillet "thereof, willhold thehead againstlany'lateral deflectlon relative to thelou'ter contour of the web. moving die is forced bar-or blank, with base 14 towardsthe against the base of the fishing section L thereof, as shown in Fig. 4,the onlyldirection in which the .metal of "the'bar'may swell is away from the outer contour of the web '12. JManifestly, therefore, 'a'llbulging or swelling of the web will be in the direction of the inner contour thereof, more or less filling'upthe spacedeetween the head '10 and the heel 216. Consequently, the low fishing bar-section L :thus

formed will include the same amount of metal and'be at leastofequal weight-and strength as the :high fishing bar section H, and all necessity of removing any metal from thebari ollowing the bulldozing operati'on is avoided. This swelling'ofthe metal of the low fishing section L "into the inner contour of the bar is illustrated in .Figs. 3

and5 oii' the drawings, from which figures it will bexnotedthatthe web ofthe low'fishingh section L, originallythesame as the web ofthelhigh'lishing-section, is of materially greater width thanthe web of thehighfishing-section and that all increaseinthe Width of the web ofthe low fishingsection is directed inwardly as at 26.

Without further description it is thought that the features and advantages .ofthe invention will be readily apparent to those skilled in'ithe-art, and it 'will'of course be understood that changes iin'i'the 'for1n, pro- L portion and minor details of construction end portions of the bar relative to one anmay be resorted to, the spirit of the invention and scope of the appended claims.

I claim:

1. The method of making a step-j oint rail splice bar which consists in subjecting a rail splice bar, having a head, a base and a connecting web, to pressure to reduce the fishing height of one end portion of the bar relative to the other end portion thereof, vertically and laterally offsetting the respective end portions of the bar'relative to one another and causing all displacement of the metal 0 the bar, incident to changing the fishing height of the aforesaid end portion of the bar to be directed toward the inner face of said end portion.

2. The method of making a step-joint rail splice bar which consists in subjecting a rail splice bar, having a head, a base and a connecting web, to pressure to reduce the fishing height of one end portion of the bar relative to the other end portion thereof, holding the outer faces of the head, the web and the base respectively, of said end portion against outward deflection while reducing the fishing height thereof, whereby all displacement of the metal of said end portion, incident to reducing the fishing height thereof, is directed toward the inner face of the bar, and vertically and laterally offsetting the respective end portions of the bar relative to one another.

3. The method of making a step-joint rail splice bar which consists in subjecting a rail splice bar, having a head, a base and a. connecting web, to pressure to reduce the fishing height of one end portion of the bar relative to the other end portion thereof, holding the outer faces of the head, the web and the base, respectively, of said end portion against outward deflection and holding the inner face of the head of said end portion against inward deflection relative to the outer face thereof while reducing the fishing height of said end portion, and vertically and laterally offsetting the respective end portions of the bar relative to one another.

4. The method of making a step-joint rail splice bar which consists in subjecting a rail splice bar, having a head, a brace and a f connecting web, to pressure to reduce the fishing height of one end portion of the bar relative to the other end portion thereof, holding the outer faces of the, head and the web, respectively, of said end portion of the bar against outward deflection and holding the inner face of the head of said end portion against inward deflection relative to the outer face thereof while reducing the fishing height of said end portion, and vertically and laterally offsetting the respective In signa without departing from other.
